MFRC52202HN1,151

The MFRC52202HN1,151 is a highly integrated Reader/Writer IC for contactless communication and supports ISO/IEC 14443 A/MIFARE mode. The internal transmitter is able to drive a reader/writer antenna designed to communicate with ISO/IEC 14443 A/MIFARE cards and transponders without additional active circuitry. The receiver module provides a robust and efficient implementation for demodulating and decoding signals from ISO/IEC 14443 A/MIFARE compatible cards and transponders. The digital module manages the complete ISO/IEC 14443 A framing and error detection (parity and CRC) functionality. The MFRC522 supports contactless communication and uses MIFARE higher transfer speeds up to 848kBd in both directions.

• Highly integrated analogue circuitry to demodulate and decode responses
• Buffered output drivers for connecting an antenna with the minimum number of external components
• Typical operating distance in read/write mode up to 50mm depending on the antenna size and tuning
• Supports MFIN/MFOUT
• Additional internal power supply to the smart card IC connected via MFIN/MFOUT
• FIFO buffer handles 64-byte send and receive
